`float` and `double` values can be formatted at compile time

Example:
------
import std.format : format;
import std.math : sqrt;

enum pi = format!"%s"(3.1415926f);
static assert(pi == "3.14159");

enum golden_ratio = format!"|%+-20.10E|"((1 + sqrt(5.0)) / 2);
static assert(golden_ratio == "|+1.6180339887E+00 |");
------

Note: It doesn't work for reals yet.
